Mackenzie McDonald, ranked 186th, broke Dimitrov's serve three times in the fourth set and pushed the fifth beyond 12 games - there are no tiebreakers in fifth sets at the Australian Open - before his first double-fault of the set gave Dimitrov a match point.
Djokovic rattled through the third set and it looked as though Monfils would quit, but to his credit he recovered his senses to offer some stern resistance in the fourth. Federer, a five-time victor, was able to swerve such conditions, however, after submitting a personal request to tournament officials.
"2017, I have said goodbye already, I am not looking back", she said after a forgettable last season that saw her relinquish the number one spot and slide down the rankings. "Possibly (I had extra leverage)".

Sharapova's unforced errors spelled her doom once more as Kerber raced off to the win and advanced to the Round of 16.

The heat tested the patience of both players during the match, while Vekic got frazzled by a wailing baby in the terraces when serving in the second set. We were also getting into some long exchanges and rallies.
Had the temperature reached 40 degrees and Wet Bulb Globe (which takes into account humidity and other factors that adds to the discomfort in high heat) reading exceeded 32.5 degrees, organisers would have stopped play on the outside courts and the roofs closed on the three main courts to provide shade. "I understand there is a factor of tickets. It feels, from a player's perspective, that you're kind of always in a rush", he said. We have to take that into consideration.
Gael Monfils said he was "dying" on court, Caroline Garcia's feet were burning up and Dominic Thiem couldn't wait to get in an ice bath as Melbourne's searing summer heat played havoc at the Australian Open on Thursday.
